We got engaged on Oct 31st, 2008 and I started planning and house hunting at the same time! We closed on our house and moved in Feb 1st, 2009, and we are getting married Sept 9,2009.
This year has been a hard one financially... but we have managed and I'm glad we did! We plan on having our AHR here at the house too.
Go with what you feel you can handle,it will all work out!
